What innovation allowed hydraulic technology to explode and be used in practical ways for the first time?

The steam shovel represents a significant innovation in hydraulic technology as it efficiently combined steam power with hydraulic principles to move earth and perform heavy lifting tasks. This machinery utilized steam engines to create hydraulic pressure, which in turn operated large, powerful shovels, revolutionizing construction and dig operations in the late 19th century.

The introduction of the steam shovel allowed for massive excavation projects to be completed more rapidly and effectively than were previously possible, demonstrating the practical applications of hydraulic technology in industries such as construction, mining, and infrastructure development. This marked a turning point in mechanized labor and laid the groundwork for further innovations in hydraulic systems.

In contrast, while options like the force pump, aqueduct, and high-pressure hose certainly contributed to the development and implementation of hydraulic concepts, they did not represent the same groundbreaking leap in practical application as the steam shovel did during its time. These alternatives primarily served specific functions within established hydraulic systems rather than igniting widespread use and advancements in hydraulic machinery across various industries.
